I recently installed a new Solis 3 Kw PV inverter coupled to the AC output of a Victron Multi. The Multi is ramping up the frequency when the battery is full, as set up in the "assistant". The Solis does not respond to frequency rise, and continues to supply power and over charging the batteries. I contacted the seller, and Solis tech help, to ask what settings I should use to make it happen. They tell me the version of the Solis made for the UK market does not support the frequency derate option. On this Solis home screen it says LimByFreq which I took to mean what it sounds like. My quetion for you is : Do you think this is right ? If you are UK based what settings did you use to achieve the power control ?
